Hi ; qmail can do a basic setup using a script ( http://www.syslogs.org/qmail/scripts/qinstaller.cnt6x.tar.gz for centos 6). In this way you can your mail server open to relay.In this way you can send notification emails. ( example for nagios etc.. ) 2014-08-01 16:17 GMT+03:00 Dan McAllister

I don't think you need qmail for that. If it's a simple relay that you want to run Id probably go for Exim4 or Postfix. They can do this simple work easily and there is probably a lot of documentation available how to set it up. For added security you should consider using firewall rules to

It is EXCEPTIONALLY easy to setup QMail as a relay: _*For inbound traffic relay:*_ - First, setup a route (in */var/qmail/control/smtproutes*) that points your domain(s) to your hidden mail server Read more about smtproutes on our website (yes, its still there)

If I understand correctly, you'd like to be able to send emails from a cloud web app to intranet (local) users. As long as the intranet users are in domains for which your mail server receives emails (the domain is in your rcpthosts), you shouldn't need to do anything special. Just set up

I think they don't wanna take any risk and loop it through an internal connection. No outside one at all. Under that aspect I see a relay being useful. It can deal with nasty stuff instead of the important machine on the LAN. Could be a security requirement in the company, maybe PCI compliance
